Title: Magnetic resonance device and its operation method
Inventor: BUITSUSHIYUNUU SHII SURIBASUTA
IPC: G01R33/3873
Filed: 1995-11-02
Abstract: PROBLEM TO BE SOLVED: To provide a short bore magnet for obtaining harmonic shims greater than Z6 and maintaining uniformity that is equivalent to a long bore magnet. SOLUTION: In a magnetic resonance apparatus comprising a short subject containing bore 12 having an axial length to diameter ratio of less than 1.75:1 and normally about 1.67:1, temporally constant magnetic field distortions generated within a bore by super-conducting magnets 10 surrounding the bore are reduced by arranging shims in shim trays disposed longitudinally around the bore 12. Each shim tray includes many shim pockets that contain ferrous shims for shimming the magnetic field in the bore. An initialization device 60 calibrates the initial magnetic field within the bore. An initial shim distribution is decided, which shims an inhomogeneous magnetic field toward a target more homogeneous magnetic field. An optimizer 66 decides a residual magnetic field from a difference between the inhomogeneous magnetic field and the target magnetic field.

Title: Audio device
Inventor: HASEOKA MASAHIDE
IPC: G09G5/00
Filed: 1998-10-30
Abstract: PROBLEM TO BE SOLVED: To provide an audio device for an automatic effective demonstration under a condition where AC power is turned on and off with a circuit breaker everyday at a store eliminating the need of turning on and off a power switch. SOLUTION: The AC power of this audio device is turned on and a microcomputer undergoes a reset process. When a prescribed time has passed and the demonstration is not prohibited (Step 5), if the audio device is in the power-off state (Step 10), a demonstration in the first function display state including the function display of a central controller and LEDs start (Step 11). If the audio device is in the power-on state, a demonstration in the restrained second function display with limited function display of the central controller and the LEDs start (Step 12). These demonstrations stop when a demonstration prohibiting operation or a function operation is conducted. When the audio device enters a demonstration prohibiting state (Step 6), the audio device waits for the power-on state (Step 7), and starts a corresponding operation when any operation key is depressed (Step 8).

Title: Copper alloy pipe for steam piping
Inventor: KURODA TARO
IPC: C22C9/04
Filed: 1996-11-05
Abstract: PROBLEM TO BE SOLVED: To obtain a copper alloy pipe for steam piping, excellent in corrosion resistance to steam, by forming a pipe by the use of a Zn-containing copper alloy, specifying P content in the copper alloy, forming Sn and Cu-Sn alloy layers on the internal surface of the pipe, and specifying the roughness of the internal surface. SOLUTION: This copper alloy pipe for steam piping is composed of a copper alloy containing, by weight, 0.01-10% Zn and having <=0.04% P content, and a protective coating layer of 0.1-3μ, composed of Sn or/and Cu-Sn alloy layers, is formed on the internal surface, and also the center line average height (Ra) of the internal surface is <=1.2μ. Although the velocity of the diffusion of Zn in a base material through the coating layer is very high and Zn is diffused into the surface layer part of the coating layer soon after the formation of the coating layer, a compound oxide of Sn-Zn cannot be formed in this state and this compound oxide of Sn-Zn can be formed only when this pipe is used as a steam pipe and brought into contact with steam, and as a result, excellent corrosion resistance can be produced.  When the above Ra exceeds 1.2μ, peeling of the protective coating layer becomes liable to occur.

Title: Magnetic recording reproducing apparatus
Inventor: TAKEDA MUNEHISA
IPC: G11B5/588
Filed: 1990-11-15
Abstract: PURPOSE:To improve the image quality by operating the driving waveform of a head based on previous errors and obtaining the driving pattern of a not reproducing side by inverting the time axis of the previous pattern of a reproducing side. CONSTITUTION:An output signal of a magnetic head 5 is, through a head amplifier 14, input to an envelope detecting circuit 15, whereby an envelope is detected. The analog signal of the output signal is converted by an A/D converter 16 and sent to an error accumulating/storing device 18. The shifting amount of the scanning position of the magnetic head to a recording track for each trial is detected, accumulated and stored. The driving of the head suitable for speed search or the like generated by a waveform generating device 17 and the accumulated error in the device 18 are inputted to a waveform operating device 19, thereby operating the waveform of the head. The driving waveform of a head actuator 4b at the last time is inversely read and added through a converter 21 and a head driver 20 for every sampling time. The head 5 is driven by a current corresponding to the driving waveform, and the current is amplified by the amplifier 14. n this manner, an error is decreased for every trial, thereby ensuring the high image quality.

Title: Planer antenna
Inventor: KANEKO YOICHI
IPC: H01Q21/06
Filed: 1988-12-08
Abstract: PURPOSE:To attain a small sized antenna with a high efficiency by providing a ridge to a groove center formed to a waveguide. CONSTITUTION:A ridge waveguide 1 consists of a waveguide main body 2 made of a metallic conductor and a sheet plate 3 covering its upper face. Then a groove 4 whose width and depth are respectively W and H is formed to the waveguide main body 2. Moreover, a ridge 5 whose width and height are respectively (t) and 1/4 wavelength or over is provided to the center of the groove 4. Furthermore, a line and a radiation element are coupled in terms of electromagnetic field by approaching the radiation element to the ridge 5. Thus, since the line width is narrow, a simple parallel feed system is adopted thereby making the arrangement interval of the radiation elements to be 0.9 wavelength or less and reducing the line loss of the feeding line to be that of a standard waveguide.

Title: Control method for electrophotographic copying machine
Inventor: MUROFUSHI TAKASHI
IPC: G03G15/00
Filed: 1986-12-26
Abstract: PURPOSE:To avoid various troubles accompanied with extinction of a flash lamp by lighting an erase lamp when a sensor, which detects whether the flash lamp is lit or extinguished, detects extinction of the flash lamp at the time of copying. CONSTITUTION:When the flash lamp is lit, a terminal A of a NAND circuit as a detecting circuit falls to the low level, and a signal in the high level is outputted from a terminal B by NAND between the input of the terminal A and that of a terminal C which receives a flash signal. Meanwhile, when the flash lamp is extinguished, the terminal B is in the low level as it is because the terminal A is in the high level as it is, and extinction is discriminated and a processing signal is outputted from a control circuit so that an erase lamp 14 is all lit. that is, if the flash lamp 1 is extinguished by some cause, the switch of the erase lamp as the extinction processing means is turned on to certainly all light the erase lamp 14. Thus, unnecessary toner sticking from a developing device 9 to a photosensitive body 7 is prevented and pollution in a machine due to scattering of the toner is avoided.

Abstract: PURPOSE:To surely switch a facsimile communication to a reception mode by inserting a pseudo CNG signal in the pause period of a CNG signal showing a non-voice terminal, stopping the sending of a CED signal when the pseudo CNG signal is detected, and sending a prescribed initial identification signal. CONSTITUTION:A control part 5 orders a switching part 2 to send the signal sent from a CNG signal transmitting part 3 to a circuit 1 based on the transmission timing of the CNG signal prescribed by the CCITT advice. The part 3 transmits the CNG signals for 0.5sec., and the part 5 sends a pseudo CNG signal of 1100Hz received from a pseudo CNG signal transmitting part 4 to the circuit 1 for Y seconds after X seconds from transmission of the CNG signal. Then the CNG signal is sent from the part 3 after Z seconds. Such CNG signals are repetitively transmitted. When the pseudo CNG signal received from the circuit 1 is detected at a pseudo CNG signal detecting part 9, the transmission of a CED signal is discontinued and an initial identification signal is transmitted. Thus the facsimile communication is surely switched to a reception mode.
